Synopsis

smtpp [-d] [-l[[@]logfile]] [-pport] [-iinternal_ip] [-eexternal_ip] [-hdefault_ip[:port]]

Description

smtpp is SMTP gateway service to allow internal users to access external SMTP servers.

Options

-I
Inetd mode. Standalone service only.
-d
Daemonise. Detach service from console and run in the background.
-t
Be silenT. Do not log start/stop/accept error records.
-u
Never look for username authentication.
-e
External address. IP address of interface proxy should initiate connections from. By default system will deside which address to use in accordance with routing table.
-i
Internal address. IP address proxy accepts connections to. By default connection to any interface is accepted. It´s usually unsafe.
-p
Port. Port proxy listens for incoming connections. Default is 25.
-h
Default destination. It's used if targed address is not specified by user.
-l
Log. By default logging is to stdout. If logfile is specified logging is to file. Under Unix, if ´@´ preceeds logfile, syslog is used for logging.

Clients

You can use any MUA (Mail User Agent) with SMTP authentication support. Set client to use internal_ip and port as a SMTP server. Address of real SMTP server must be configured as a part of SMTP username. Format for username is username@server, where server is address of SMTP server and username is user´s login on this SMTP server. Login itself may contain ´@´ sign. Only cleartext authentication is supported, because challenge-response authentication (CRAM-MD5, SPA, etc) requires challenge from server before we know which server to connect.
